Hello to everyone,I'm working on displaying JPEG files using STM32H745BIT6 chip. I successfully configured all peripherals (LTDC, DMA2D, HW JPEG decoder) and now I'm able to dislay JPEG data. At first JPEG decoder converts JPEG data to YCbCr data and...
Hi everybody,I'm developing a simple gui on an STM32F429 microcontroller with the use of the STemWin grapich library. Everything is working well till I'm using just one framebuffer; now I would like to use double buffering to optimize the interface a...
Hi,I have a question related to the graphic engine DMA2D in the STM32H743. The STM32H743 custom board has the video analog chip (ADV7180KCP32Z-RL). It sends the YCBCR video data to STM32H743 through DCMI interface.1. We are able to receive the YCBCR ...
Hi all, we have a custom made STM32H7A3 board and have an issue with the TouchGFX screen display: The display flickers heavily with every new screen it should display, after a short time it is stabilized and ok.Components and Setup:STM32H7A3 at 280 M...
Hi folks, we had made a custom STM32 board and we had some issues setting up TouchGFX. Used Components:Display parallel interface with 800 x 480 pixelsMCU: STM32F429BITSDRAM: IS42S16400J-7TLCubeMX Settings:FMC for SDRAMLTDC for Parallel 888 DisplayDM...
Hello allI have a custom STM32L496RGTx-based board onto which I'm migrating a legacy rendering engine. I'd really like to accelerate text rendering and I'm looking into DMA2D for a4 format font data.I have a little test setup which attempts to popula...
Hi all,We are testing the failure modes for the OCTOSPI memory mapped mode and there isn't much info in the documentation.The setup:* STM32L4S9ZIJ6* Dual external RAM chips (CY15B104QSN) configured for dual QPI DTR.* External memory used for TouchGFX...
During the normal operation of the program, after touching the pin on the external sdram by hand, the UI screen is stuck. The simulation shows that the DMA2D Transfer error flag is set, touchgfx cannot work normally, and the chip works normally after...
I am using STM32H745 with 16bit SDRAM and QSPI nor flash for images and TouchGFX for developing the screens. Am using 800x480 resolution.I have developed some sample screens which look fine when 565 color mode is configured in LTDC and DMA2D and Touc...
In an attempt to find a problem with the DMA2D causing display issues (random pixels showing), I have turned on the interrupt handler DMA2D_IRQHandler() with the following code to allow me to halt debugging inside the routine when needed:void DMA2D_I...
